You're probably very inexperienced playing an Awakened character, then. While knowing how to use a gun is important, it's very easy to cast spells the entire run with only minimal drain (or no drain) by picking lower-Force spells. If someone has 9+ Drain Resist dice, that's 3 hits on average. That's a F6 Clout (or any other single-target LOS Indirect Combat Spell), or F8 if you learn it Limited. Nine is also quite low for Drain Resist; usually I see if at 11 or above, especially when you combine it with sustained Increase Attribute spells. So I'm afraid you're wrong about magic not standing on its own; when you take into account doing all of this while having one or more (via Binding) spirits backing you up, it becomes clear why "Geek The Mage" is still a street motto. Someone who can cast Health spells can usually have 14+ dice (6 LOG/INT/CHA, 4 WIL, Increase Willpower F4) and then easily get away with F7+ combat spells every turn, or even higher if they learn one as Limited. If you're concerned about losing your casting fetish, you can learn the same (or a different) spell in normal, non-limited format.
If you've made a Logic magician and have the leftover skillpoints and nuyen to be anything resembling a decker, you probably can't rely on magic because you simply chose not to invest in it.
Also, the vast majority of magician characters are not expect to regularly lose access to their magical abilities. You do reminds me that the tradition limitations like that in Forbidden Arcana do nothing to say what happens if you break them. Though the only one you can really have forced upon you would be "staying in one place for more than a week", which is actually too vague to mean anything. Is the "same place" a street? A house? A room? The entire sprawl? The district? It's dumb.
